My .02 - probably, although <> says:

> A sender must not generate a trailer that contains a field necessary for message framing (e.g., Transfer-Encoding and Content-Length), routing (e.g., Host), request modifiers (e.g., controls and conditionals in Section 5 of [RFC7231]), authentication (e.g., see [RFC7235]and [RFC6265]), response control data (e.g., see Section 7.1 of [RFC7231]), or determining how to process the payload (e.g., Content-Encoding, Content-Type, Content-Range, and Trailer).

... which kind of already goes there. Maybe just note that they fall under that requirement?
